The Middle Cerebral Artery Blood Flow of the Fetus in RH-Immunization
Abstract
One of the complications of pregnancy is the so-called Rh-conflict between mother and fetus. This conflict is due to the fact that the body of a Rh negative (Rh-) pregnant woman rejects a Rh positive (Rh +) embryo due to a misunderstanding on the part of the mother's immune system. In order to assess the risk of developing Rh-conflict and understand the methods of its prevention, it is necessary to understand how our immune system works, what a blood group is and how the Rh factor works. The child inherits the Rh factor from one of the parents. The Rh factor of the fetus is determined in the womb, when the formation of the circulatory system begins. If the parents have the same factor, the child will not have problems. With a negative rhesus in the father, even if the fetus inherits it, nothing dangerous also happens. Problems begin if the mother has a negative rhesus, and the father is positive, and this positive factor is passed on to the child. The maternal immune system begins to attack the fetus. The provision of specialized care for pregnant women is a priority area of modern obstetrics. In the structure of perinatal morbidity and mortality, the immunological conflict as a result of Rh sensitization and group incompatibility stably ranks 5-6.
